Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to an anti-blocking and mud-discharging device for a sewage treatment sedimentation tank. Background Art
[0002] Various forms of sedimentators are used in sewage treatment. Currently, most of these sedimentators use mud discharge horizontal pipes or large-diameter straight pipes with small holes of 20-30mm in diameter evenly installed at the bottom of the sedimentator to complete the mud discharge operation. Because the suspended matter contained in the sewage has a high specific gravity, it will cause the sediment to accumulate on the plate and cannot slide. It is easy to clog at the straight pipe mouth, resulting in poor mud discharge from the sedimentator, which seriously affects the continuous working ability of the sewage treatment. Utility Model Content
[0003] In order to solve the above technical problems, the utility model provides a sewage treatment sedimentation device to prevent blockage and discharge mud, and the technical solutions adopted are as follows:
[0004] A sewage treatment sedimentation tank anti-blocking and mud discharge device includes a main pipe arranged at the lower end of the sedimentation tank, the lower end of the main pipe is connected to a first motor through a flange, and a first screw connected to the first motor is provided inside the main pipe; a connecting pipe is provided on the side of the main pipe, one end of the connecting pipe is connected to a branch pipe on the side of the mud discharge pipe, a second motor is connected to one end of the mud discharge pipe, a sealing cover is provided at the other end of the mud discharge pipe, a second screw transmission-connected to the second motor is provided inside the mud discharge pipe, and a mud discharge port is opened in the middle of the mud discharge pipe.
[0005] Furthermore, the upper end of the first screw is placed inside the sedimentator, and can fully scrape out the sludge inside the sedimentator.
[0006] Furthermore, the discharge port of the connecting pipe is arranged to be tilted downward, so as to facilitate the transportation of sludge from the connecting pipe to the sludge discharge pipe.
[0007] Furthermore, an inclined mud guard is provided in the mud discharge pipe and at the mud discharge port, and an opening is provided in the mud guard for the central axis of the second screw to pass through. The inclined mud guard facilitates the discharge of sludge more smoothly and can reduce the residual sludge at the mud discharge port.
[0008] Compared with the prior art, the present invention has the following beneficial effects:
[0009] The utility model can scrape out the sludge at the center position of the bottom of the sedimentator through the first screw. As the sludge slides, the surrounding sludge will slide toward the center position of the sedimentator, so that all the sludge inside the sedimentator can be scraped out. The scraped sludge can be pushed into the sludge discharge pipe by the push of the first screw. The sludge pushed into the sludge discharge pipe by the second screw is discharged from the sludge discharge port. The cooperation of the first screw and the second screw can smoothly scrape out the sludge in the sedimentator, thereby ensuring the continuous operation of the sewage treatment in the sedimentator.
